摘　　要：目的:探究油茶皂苷与月桂酰肌氨酸钠(Sodium lauroyl sarcosinate,SLS)之间的协同作用。方法:考察油茶皂苷的加入对复配体系表面活性的影响,并探究复配体系在不同条件下的稳定性。结果:复配体系中加入质量分率(α_(1))为1%的油茶皂苷时,其临界胶束浓度(Critical micelle concentration,CMC)增效12.35%,表面张力(γ)比SLS低4.12%;体系的接触角为23.9°,相比于油茶皂苷的接触角减小23°,润湿性大幅提升。当α_(1)为1%、10%时,发泡体积相比油茶皂苷分别增效85.04%、72.68%。在α_(1)=4%时,泡沫稳定性相较于SLS增效11.35%。油茶皂苷-SLS复配体系在高温下稳定性优异,具有良好的抗硬水能力;在盐离子和酸性条件下,复配体系的CMC显著降低,表面活性提高。结论:油茶皂苷-SLS复配体系在表面活性上存在良好的协同效应,油茶皂苷的生产及应用不仅有利于日用化学工业的发展,而且对充分开发利用茶籽饼这一天然资源具有较大的实际意义。Objective:The work aims to explore the synergistic effect between Camellia oleifera saponins and sodium lauroyl sarcosine(SLS).Methods:The effect of Camellia oleifera saponins on the surface activity of the compound system was investigated, and the stability of the compound system under different conditions was explored.Results:When Camellia oleifera saponin with mass fraction(α_(1)) of 1% was added into the compound system, the efficiency of the critical micelle concentration(CMC) improved by 12.5%, and the surface tension(γ) is 4.12% lower than SLS. The contact angle of the compound system was 23.9°, decreased 23° compared with Camellia oleifera saponins, and the wettability was greatly improved. When the value of α_(1)is 1% and 10%, the foaming volume increased by 85.04% and 72.68% respectively compared with Camellia oleifera saponins. When the value of α_(1)is 4%, the foam stability increased by 11.35% compared with SLS. The Camellia oleifera saponin-SLS compound system has excellent stability under high temperature and good resistance to hard water. Under the conditions of salt ion and acid, the CMC of the compound system decreased significantly and the surface activity increased.Conclusion:The Camellia oleifera-SLS compound system has a good synergistic effect on surface activity.The production and application of Camellia oleifera saponin is not only conducive to the development of daily chemical industry, but also has great practical significance for the development and utilization of Camellia oleifera seed cake.
